Upgrade from a Vector pedal-based power meter to a dual-sensing Vector 2 system. Available to fit both standard (12-15 mm) and large (15-18 mm) crank arms, upgrading allows cycling enthusiasts to take that next step in measuring and monitoring their power output and pedaling style.

Easy to Buy, Install, Own

Upgrading Vector is easy. You can install it yourself in minutes. There’s no need for a mechanic, or no downtime while your bike is in the shop. There are no complex drivetrain or wheel tradeoffs, or no external sensors to install.

Behind the Watts

Vector works by measuring the deflection in the pedal spindle as you pedal. By comparing that measured deflection to a factory calibration, Vector can determine how much force you’re applying to the pedal. It measures a few hundred times per second. Built-in accelerometers also measure your pedaling cadence. The force sensor and related electronics are permanently and securely sealed within the pedal spindle.
